In this yuletide episode Jasmine and Piers don their Christmas jumpers and compare notes on favourite festive ads, focusing unashamedly on British retail ads because, let’s be honest, they are the best Christmas ads in the world. From Keira Knightley meeting her match over charming cheese to the much talked about John Lewis ad (which made Piers cry but don’t tell anyone) to Dawn French stuck in traffic, we review the ads and argue over what score to give them.
